HEPER FQR LOCK-BOLTS.

Specification of Letters Patent.

Patented Apm`121, 1908.

I Application filed April 15, 1907. Serial No. 368,420.

T o all whom it may concern:

Be it known that I, JAMES Ciinisrr, a citi- .lzen of the United States, residing at Chicago,

in the county of Cook and State of Illinois, have invented a new and useful improvement in Keepers for Lock-Bolts, of which the lollowing 1s a specification.

.pending application for Letters rial `Number 354,923, filed January 30, 1907,

M invention relates to an improvement on t e construction of keeper for door-locks of the variety forming the sub'ect of my atent, Se-

My primary object is to improve upon the means set forth in said ending ap lication, for releasably 'securing the relative y adjustablel members together in adjusted position.

Referring to the accompanying crawing-- `Fignre 1 is a broken face view of a door-j amb provided with my improved keeper; Fig. 2, a face view of the rear member ot the keeper shown 1n Fig. 1, with a portion of one end y broken away .to showa detail; Fig. 3, a face View of'the adjustable front member of the kee er shown in Fig. 1; Fig. 4, an edge view of t e rear member, viewed in the direction of the arrow as indicated at 1 on Fig. 2; Fig.

' 5, a similar view of the adjustable member,

viewed in the direction of the arrow as indicated at 5 on Fig. 3; Fig. 6, a broken section vtaken at the line 6 on Fig. 1,` viewed in the direction of the arrow Fig.' 7, an enlarged broken section taken at the line 7 on Fie'. 1 and viewed in the direction of the arrow; `ig. 8, an enlarged erspective view of' the rear face of one of t e eccentric locking washers emplo ed, and Fig. 9, a similar view of the front aceof the washer.

As in the construction set forth in my said. application, the present device comprises a rear 0r inner member l1() adapted to bc pei'- manently secured to a door-Jamb, or dooredge, and a front or outer member 11 adjustably supported on thc member 10. The member '10, which is best formed of sheetbrass, is of a general rectangular shape, having a central struck-up Aiortion 12 provided with an opening 13. This member is provided at opposite ends with recesses 14 and 15, oft e member upon itself, to afforr outer vand inner Walls 16 and 17.

'In the present construction, there is provided in each wall 16 near the ende of the lnember 10, circular openings 1S having beveled edges 1Q, and in which eccentric reduced by bending each endortionlocking washers 2() are removably confinedv for' the purpose hereinafter described. In the washers are centralscrew-holes 21 registering and concentric with screw-holes 22 in the walls 17, at `which screw-holes the ineinber 10 is adapted to be secured, as by screws 23, in a recess 24 provided in a door-jamb 25.

:Ea-'ch washer has its circumferential edge beveled at the same anglo as the edge of the opening 1S which receives it, as shown at 26, and is provided with an eccentric boss 27 on its rear face for engagement with the member 11, as hereinafter described.

The adjustable member 11 has a struck-up central portion 28, this portion being struckup for a greater length than the portion 12 of the inner member 1() with which it registers, whereby the spaces 12n are provided between the ends of the portions 11 and 12.

`The central portion provided with the usual cam-extension 2) and has catch-bolt and lock-bolt-recciving openings 30 and 31, respectively. These openings, which are relatively narrower than the opening 13, register with it, when the parts of the device are assembled as hereinafter cxplained. The ends of the member 11 which arc slightly narrower than the ends of the member 1() and reach short of the end-walls of the recesses 14 and 15, areprovidcd with transversely and longitudinally elongated slots-32 which register with the screw-openings 22 and through which the attaching screws 17 pass, and into which the eccentric bosses 27 extend to engage the side walls of the slots when the member 11 is positioned on the member 10.

The arts are assembled before the device is ap hed in operative position; and to accomp ish this the members 10 and 11 are laterally tclescopcd by inserting' the ends of the member 11 edgewiso into the recesses 14 and 15, and thus between the walls 16 and 17 of the member 10, and drawing thc members together to thc position represented in Fig. l, in which the member 11 lies flatwise against the member 10, with its opening 13 registering with the openings 30 and 31. The washers are then inserted into the openings 18 and artially rotated or set therein to cause the ossee 27 to enter the slots 32. The member 10, thus carrying the member 11, is then sethe members 1t) and 1l and the washers 20, the beveled surfaces of the washers and openings 1S serving to draw the walls lo and walls 17 togetherto clamp the ends of the melnber ll between them; and toenhanee' the clamping-hold, the surfaces of the end-portions of i the member l t may be roughened` as represented at Bit, as also the inner surfaces of the 5 walls lt and l7as represented at 34. When, for any reason. remljustmentof the member ll is desired. the screws 23 may be slightly \\'ithdrawn, therebv removing the pressure of the walls lt and lT against the end-portions of the member 1l and allowing tbe bosses to be disengaged from the slots in the member ll, whereupon the latter may be moved up and down and laterall)r to the desired position on the member lt), in which adjusted position it ma)Y then be clamped by lirst turningr the washers in the openings 1S to cause the bosses 27 to again enter the slots 32 and then tightening the screws.

By forming the struck-up portion of the outer member of a greater length than' the struck-up portion of the inner` member, as dei scribed, the construction is rendered more v effective in its purpose, jmrtienlarljY because of the desirable s vnnnetrjv it. all'ords to the device.

It is obvious that b v providing 'the eccentric washers with the bosses for engaging the slots in the member ll, slipping of this member on the inner member, when the keeper is in use, is entirely obviated, this being a very import ant feat-ure, especially when the keeper is used in connection with heav \Y doors.
